Fresh install not recognizing text like before

[Votum V]

I've been using tesseract for a while now to read text from images that I take with a script for a game I am automating. I recently had to do a fresh install of my windows machine which included re-installing tesseract on my system.

The problem is that the same images that we're parsed and converted from an image to text are no longer being parsed correctly...

For example, one of the use cases here is taking a picture of a region in the game that contains a string like "Lv. 15", this worked fine before, but is now returning "Nn" or "Aa" pretty consistently...

I'm just curious if anyone else has experienced something like this? I'm quite lost on what to do about this because the software is also working for other people who use my script (their tesseract is parsing out the correct values).

Some information in case it helps...

System: Windows 10 x64

Please also provide tesseract version information from a machine where it is working.

Please also check that the traineddata file being used is the same. You can compare filesizes as the name is the same.

Your tesseract version seems to be strange (should be tesseract 5.0.0-alpha-551-g99df, but instead of git revision you have date) How did you get it?

Please also provide input image for testing, command/code how you extract text from image and maybe more relevant information  (e.g. with reinstalling tesseract you must change something...) 

Without details that enable to replicate problem there is no way how to help you.
